I loved your baby tree helper idea. Adopting young animals, baby trees,
newly planted areas in general - this is a great way to foster longterm
projects since to be successful, you have to monitor these places somehow.
Might be a good way to steer some epemeral artworks onto your hills,
encouraging people to respect the emerging forest. Unfortunately, in the
environmental community, there is a strange connection between "young
growth" and unhealthy forest communities in that most of the ancient
forests are gone and the forest industry promotes "young growth" at the
expense of the big remaining trees. So, the trick is to find a balance
between these. This is true in any forest.
